'1 Claims. (or. 34-26) Our invention relates to hair drying apparatus of the type used for rapidly and effectively drying the human hair after it has been washed or otherwise treated, and it has among its salient objec'ts to provide a number of individual drying units all connected with and operated from a common heating plant, whereby a minimum cost of operation can be secured, and whereby individual control can be had with ease and convenience.

Other objects of our invention are: to provide a drying apparatus in which hot and cold air can be delivered together in mixed condition around the head of the person whose hair is being dried,

with means for regulating the temperature of said air and with means for delivering cool air around the face of said person, whereby to make the process more comfortable; to provide an apparatus of the character referred to in which warm air can be delivered in the hood of the apparatus from one position and sucked out from another position, thus not only circulating warm air within the hood and around the head of the person, but also drawing in atmospheric air around the face and head of said person and discharging it in the room or elsewhere, as may be desired; to provide a hood within which the human head is positioned during the drying operation, which hood has around its lower edge an annular chamber member with outlets in its inner face for the passage of air around the face and head of the person receiving the treatment; to provide a hood of the character referred to which can be adjusted as to its height so as to be more accurately positioned and adjusted to the head; I to provide a hood in which two air conduits are connected therewith side by side, and which hood can be hingedly moved or raised, or which can be turned; and, in general, to provide a. simple, practical and effective drying apparatus of the character referred to.

In order to fully explain our invention, we have illustrated one practical embodiment thereof on the accompanying sheet of drawings, which we will now describe.

Figure 1 is a plan view of an apparatus'embodying our invention;

Figure 2 is an enlarged sectional view of one of the hoods, taken on line 2-2 of Fig. 1';

Figure 3 is a cross sectional view thereof taken on line 3-3 of Fig. 2; and Figure 4 is a sectional view taken on the line 4-4 of Fig. 2.

invention as here shown for purposes of explanation, includes an oven or heating plant, des- Referring nowin detail to the drawing, our" ignated 5, for furnishing heated air. This may be of any suitable type which will furnish the desired amount of hot air. The housing 6, is connected at 1, to a fan casing 8, having the usual discharge pipe 9. A second fan casing I0, is 5 mounted in axial alinement with said first fan casing whereby both fans can be driven from a common shaft II, from a'motor l2. Said second fan casing H] has a discharge pipe l3, and both of said discharge pipes 9 and I3, connect side by 10 side with a conduit casing I, having therein a. partition 15 forming two air conduits I6 and H, which are connected, respectively, with said pipes 9 and i3 from said fans. The outer fan casing in is provided with an intake box I8, with provi- 15 sion at I8 to connect a pipe thereto for suction purposes. It is intended that the pipe l3 be adapted to be transferred .to connect with said intake box I8, for a purpose hereinafter again referred to. 20

Upon said conduit casing i4, it is intended to mount a series of drying units or hoods, which I will now describe, one of these being shown in enlarged sectional form in Fig. 2, and consisting of a tubular standard l9, having a flange l9 at its 25 lower end by means of which it is secured to the casing 14, as by means of bolts 20, 20, said tubular standards l9 having a middle partition 2|, and terminating in straight end formation to receive therein two semi-circular pipes, 22 and 23, shown 30 in section in Fig. 3, said pipes 22 and 23 connecting at their lower ends with the two chambers or conduits I6 and H, as seen in Fig. 2. Around said standard l9, and said semi-circular pipes 22 and 23 is the straight tubular portion 24' of an 5 elbow 24, with set screws at 25 and 26 for securing the upper ends-of the inner pipes 22 and 23 thereto. The lower end of said elbow 24' is provided with a flange portion 24 shown resting upon the flange portion IQ of the standard l9, while 40 a set screw 21 is shown in said elbow 24 for holding it in its down position, as indicated. A coiled spring '28 is shown interposed around the two semi-circular pipes 22 and 23, within the elbow section 24' and bearing at its lower end 45 upon the upper end'of the standard 19, and at its upper end against the bosses 25' and 26' in which the set screws 25 and 26 are placed. This spring is for the purpose of raising the elbow 24, when the set screw 21 is released, for the purpose 50 of adjusting the drying hoods'up and down to better accommodate the-customer whose hair is being treated. The elbow 24, inits upper portion, is also provided with a partition, as 24 with two wing damper members 29 and 30, 55

hingedly connected thereto, and provided with operating heads, as 29' and 30', Fig. 4, for turning said wing dampers to close one or the other or both of the passageways or conduits through said elbow, as will be clear from the drawing. Each of said operating heads is provided with a small coiled spring as at 3|, for yieldingly holding them in opened or closed position, as will be readily understood from the showing.

In the end of said elbow 24, are also mounted two damper or valve members, 32 and 33, on pivot rods 32' and 33 across said pipe or elbow and said upper and lower air ways, as clearly illustrated, whereby said damper members can be turned up or down or straight back for controlling the flow of air from the two conduits or passageways into the hood, now who described.

The hood, as here shown, comprises an outer body member 34, provided on its top side with a heavy portion 35, by means of which it is hingedly connected with the elbow, as at 36, said heavy portion 35 being shown of annular form and fitting against the end of the elbow substantially with the hinge rods 32' and 33', as shown. An

innermost shell 39 is shown, secured around its edge with the intermediate shell 31, said innermost shell being provided with a series of openings 40, for the purpose of admitting air to said hood and the drying chamber thereof. Around the edge of said hood is provided an annular chamber member 4|, communicating with the air chamber as, between the body :4 and the intermediate shell 31, said annular chamber member 4| having outlets 42 in its inner face, substantially as shown. Said annular chamber or member 4|, forms a tapering edge for the hood, and provides means for discharging cool air inwardly around the face of the customer, as will be againreferred to. In order to provide suitable vents from 'said hood, we have shown two vent tubes, as 4 3 and 44, which connect through the different shells, as clearly indicated.

The use and operation of our invention may be briefly described as follows:

I Assuming that the parts are adjusted as shown in full lines in the drawing and that hot air is being forcedupthrough pipev 22, and cold air is being forced up through pipe 23, of the elbow 24,

the hot air will be 'discharged into the inner chamber of the head or hood, betweenshells 31 and 39, and also cold air will be forced into this chamber, the damper 33 being shown open, and part 01 the cold air will pass into the chamber 38 and thence into the annular member and chamber 4 I, and be discharged through the openings 42 around the face of the customer, while the mixed hot and cold air is being discharged through the larger openings 4|) and into the hair of the customer.

,By turning the valve or damper 32 down, hot air can be discharged into the chamber and into the annular chamber 4|, and out through the holes 42, and then, if the pipe I3 is disconnected from the fan case I, and connected to the intake box l8, as indicated in light broken lines, there will be set up a suction through the cold air conduit 23, which is applied to the hood and through the larger openings 40, and if the valve 33 is also turned down, it is possible to discharge hot or warm air through chamber 38 and through the annular member 4|, and to cause suction within the hood through pipe 23, to draw said hot air down to the intake box l8, and discharge it at the fan case at l3, from which the pipe has been removed to connect with the intake at l8. Thus by adjusting the dampers of valves 29 and 3|), 32 and 33, it will be seen that many combinations can be had and that cold and hot air can be mixed and discharged into the hood, or the air can be discharged around the annular chamber 4| and sucked in through the hood openings 40 'and drawn off. and that the temperature of the air can be regulated by means of these valve adjustments and as desired to suit the comfort of the user. It will also be noted that each hood can be adjusted as to its height and separately controlled as to the amount and temperature of the air, and also that the hood can be rotated to different positions, if desired. All hot, or all cold air can be forced into the hood by raising either of the larger damper or valve members 29 or 30, as the case may be.

We do not limit our invention, however, to the details of construction and arrangement shown for descriptive purposes, realizing that many changes can be made without' departing from the spirit thereof,'except as we may be limited by the hereto appended claims.
